e.13 odd sized chainrings - Are they the magic numbers?

Jul 4, 2008

2008 saw the launch of e.13’s range of guide rings in odd sizes, aimed squarely at the singlevspeed and racer market. But do the odd sized chain rings really make the difference and are they as ‘groundbreaking’ as e.13 seem to claim?

Here are my thoughts,

Initial thoughts of the chain ring were nothing short of spectacular, with a high quality finish that e.13 are now renowned for. The odd sized guide rings share the same lightweight characteristics as their standard e-13 guide ring counterparts and sport subtle laser etched e.13 logos against their ‘champagne’ colored body. My 37t guide ring weighed in at just under 48g, not bad at all!

Upon fitting the ring, I did however find the compromise made to achieve such a low weight, with a tooth breaking off before the chain ring had even been ridden. However I shall put that down to a manufacturing fault perhaps. Now on my second guide ring, I can’t fault it for its racing characteristics; it really does tick all the boxes. It's lightweight, 7075 T-6 aluminum construction means that it fits perfectly into a lightweight race build, whether it be for 4X or Downhill. It boasts a sleek and elegant look without screaming for attention and best of all gives a choice of chain ring size and gearing ratio that was previously either too expensive or heavy through other brands, but is now available in legendary e.13 quality. This now means you can achieve that perfect stomping or gating gear easily without spending excessive amounts.

“All right, all right, but does 1 tooth really make all that much difference?” Yes, I believe it does. It allows you to have the choice to pick the exact gear you want without pondering between a 36 and a 38 for example. Many people on the race scene also compliment the odd sized chain rings on how they enable riders to gate perfectly, ultimately leading to a better race run, and if that’s the difference 1st can make, then it certainly is a worthwhile change in my opinion.

Overall, another great product from e.13 that gives the consumer more choice, which is always a good thing. I will do a follow up review to report back on the long term durability of the chain ring over the coming months.

Odd-sized guide rings are available in 33t, 35t, 37t, and 39t options. All e.thirteen chain retention systems are compatible with the odd-sized guide rings. The rings come in at $34.50 to $36.25 and $29.99 in the UK and are available exclusively in the UK through SilverFish

 could these be used to get rid of a chain tensioner on a single speed set up i was running a 32 16 and could not get the chain tight without at tensioner even with a half link chain maybe if i was running a 33t it would work not sure

 it probably wouldnt work as the chain will still stretch even with the odd size

 blackspire has been making these sizes for years! These are nothing new guys. Blackspire rings are way stronger, less expensive. Made in Canada from high grade 7075, not that chinese faux metal those taiwan clowns pawn off on americans.

 To be fair to the e13, these chainrings are marketted as a product for racers.

Not dirtjumpers/etc


They are light.

This weight saving comes with a compromise......


They are great chainrings and the overall quality control is good!
